Solid component

Bought a batch for our workshop. Most worked perfectly, one needed sensitivity tuning.

Good value for money

Works well for hallway lighting. The blockade time is fixed but acceptable for most uses.

5 FAQ

Q: Can this sensor be used outdoors?

A: The module itself is not waterproof. You must use a waterproof enclosure for outdoor installation.

Q: Is this compatible with Raspberry Pi GPIO?

A: Yes, the output is 3.3V TTL which is safe for Raspberry Pi GPIO pins.

Q: What are the trigger modes available?

A: It supports single trigger and repeatable trigger, selectable via a jumper cap on the PCB.

Q: How do I change the detection range?

A: Use the 'S' potentiometer on the board. Turn clockwise to increase distance.

Q: Does it detect motion through glass?

A: PIR sensors generally cannot detect infrared heat signatures through glass effectively.
